Nuclear Power Summary
Nuclear power is generated using Uranium, which is a metal mined in various parts of the world.
Some military ships and submarines use nuclear power
How it Works
The reactor uses Uranium rods as fuel, Neutrons smash into the nucleus of the uranium atoms, which split in half and form energy in the form of heat.
The steam drives turbines which drive generators.
| Advantages Nuclear power costs about the same as coal, so it's not expensive to make. Does not produce smoke or carbon dioxide, so it does not contribute to the greenhouse effect. Produces huge amounts of energy from small amounts of fuel. Produces small amounts of waste. Nuclear power is reliable. | Disadvantages Although not much waste is produced, it is very, very dangerous. It must be sealed up and buried for many years to allow the radioactivity to die away. Nuclear power is reliable, but a lot of money has to be spent on safety - if it does go wrong, a nuclear accident can be a major disaster. people are increasingly worried. |
